Code from NetBSD has been included in countless other projects, Open Source and otherwise.

I've said this before, but there is a tremendous glut of fantastic OSes and applications in the FOSS world -- both BSD and Linux projects (and others). They compete and feed off one another, which makes for an interesting ongoing relationship.Thu, 20 Mar 2008 17:28:00 GMTdonotreply@osnews.com (anomie)CommentsKudos NetBSDhttp://www.osnews.com/thread?305847

http://www.osnews.com/thread?305854Looking at the proposed timelines for NetBSD; I have seen the NetBSD/usermode is "pencilled" to the next 5.0 release (scheduled for Q4/2008).

That is a very nice feature that will allow having several virtual NetBSDs running on top of NetBSD on several architectures, on top of Linux, or, maybe, on top of Interix...
